Are you being deliberately obtuse? My objection is to how your description needless obscures that the North was a mixed economy based on mostly free by also decidedly slave labor.
Surely you know there's a long history of Yankees taught that they were on the good side, because they didn't want anything to do with slavery, because that's the more comfortable history to teach, rather than the real history of how many Yankees profited off of slave-made goods, just like those English not-so-gentle-men still honored today whose wealth was built on the backs of black slaves.
Surely you are also aware that apologists for the treasonous Confederacy say the Union should have just waited a few decades for slavery to reach its natural dead end, rather having all those poor white boys die for a few black folk.
Given that knowledge, please try to not sound like a supporter of either false narrative.
